PrintDocumentInfo

---

Kotlin |Java

public final class PrintDocumentInfo
extends Object implements Parcelable

java.lang.Object
↳	android.print.PrintDocumentInfo

---

This class encapsulates information about a document for printing purposes. This meta-data is used by the platform and print services, components that interact with printers. For example, this class contains the number of pages contained in the document it describes and this number of pages is shown to the user allowing them to select the range to print. Also a print service may optimize the printing process based on the content type, such as document or photo.

Instances of this class are created by the printing application and passed to the PrintDocumentInfo, boolean) callback after successfully laying out the content which is performed in PrintDocumentAdapter.LayoutResultCallback, android.os.Bundle).

An example usage looks like this:

 . . .

 public void onLayout(PrintAttributes oldAttributes, PrintAttributes newAttributes,
         CancellationSignal cancellationSignal, LayoutResultCallback callback,
         Bundle metadata) {

        // Assume the app defined a LayoutResult class which contains
        // the layout result data and that the content is a document.
        LayoutResult result = doSomeLayoutWork();

        PrintDocumentInfo info = new PrintDocumentInfo
                .Builder("printed_file.pdf")
                .setContentType(PrintDocumentInfo.CONTENT_TYPE_DOCUMENT)
                .setPageCount(result.getPageCount())
                .build();

       callback.onLayoutFinished(info, result.getContentChanged());
   }

   . . .

Constants

CONTENT_TYPE_DOCUMENT

Added in API level 19

public static final int CONTENT_TYPE_DOCUMENT

Content type: document.

A print service may use normal paper to print the content instead of dedicated photo paper. Also it may use a lower quality printing process as the content is not as sensitive to print quality variation as a photo is.

Constant Value: 0 (0x00000000)

CONTENT_TYPE_PHOTO

Added in API level 19

public static final int CONTENT_TYPE_PHOTO

Content type: photo.

A print service may use dedicated photo paper to print the content instead of normal paper. Also it may use a higher quality printing process as the content is more sensitive to print quality variation than a document.

Constant Value: 1 (0x00000001)

CONTENT_TYPE_UNKNOWN

Added in API level 19

public static final int CONTENT_TYPE_UNKNOWN

Content type: unknown.

Constant Value: -1 (0xffffffff)

PAGE_COUNT_UNKNOWN

Added in API level 19

public static final int PAGE_COUNT_UNKNOWN

Constant for unknown page count.

Constant Value: -1 (0xffffffff)

Fields

CREATOR

Added in API level 19

public static final Creator<PrintDocumentInfo> CREATOR

Public methods

describeContents

Added in API level 19

public int describeContents ()

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of writeToParcel(android.os.Parcel, int), the return value of this method must include the CONTENTS_FILE_DESCRIPTOR bit.

Returns
int	a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either 0 or CONTENTS_FILE_DESCRIPTOR

equals

Added in API level 19

public boolean equals (Object obj)

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

• It is reflexive: for any non-null reference value x, x.equals(x) should return true.
• It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
• It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
• It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
• For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Parameters
obj	Object: This value may be null.

Returns
boolean	true if this object is the same as the obj argument; false otherwise.

getContentType

Added in API level 19

public int getContentType ()

Gets the content type.

Returns
int	The content type.

See also:

• CONTENT_TYPE_UNKNOWN
• CONTENT_TYPE_DOCUMENT
• CONTENT_TYPE_PHOTO

getDataSize

Added in API level 19

public long getDataSize ()

Gets the document data size in bytes.

Returns
long	The data size. Value is 0 or greater

getName

Added in API level 19

public String getName ()

Gets the document name. This name may be shown to the user.

Returns
String	The document name. This value cannot be null.

getPageCount

Added in API level 19

public int getPageCount ()

Gets the total number of pages.

Returns
int	The number of pages. Value is -1 or greater

See also:

• PAGE_COUNT_UNKNOWN

hashCode

Added in API level 19

public int hashCode ()

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.

The general contract of hashCode is:

• Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
• If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
• It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

Returns
int	a hash code value for this object.

toString

Added in API level 19

public String toString ()

Returns a string representation of the object.

Returns
String	a string representation of the object.

writeToParcel

Added in API level 19

public void writeToParcel (Parcel parcel, 
                int flags)

Flatten this object in to a Parcel.

Parameters
parcel	Parcel: The Parcel in which the object should be written. This value cannot be null.
flags	int: Additional flags about how the object should be written. May be 0 or Parcelable.PARCELABLE_WRITE_RETURN_VALUE. Value is either 0 or a combination of Parcelable.PARCELABLE_WRITE_RETURN_VALUE, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
