Enum DataDescriptorType

java.lang.Object

java.lang.Enum<DataDescriptorType>

com.android.tools.build.apkzlib.zip.DataDescriptorType

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<DataDescriptorType>

public enum DataDescriptorType
extends java.lang.Enum<DataDescriptorType>

Type of data descriptor that an entry has. Data descriptors are used if the CRC and sizing data is not known when the data is being written and cannot be placed in the file's local header. In those cases, after the file data itself, a data descriptor is placed after the entry's contents.

While the zip specification says the data descriptor should be used but it is optional. We record also whether the data descriptor contained the 4-byte signature at the start of the block or not.

Enum Constant Summary

Enum Constant and Description
DATA_DESCRIPTOR_WITH_SIGNATURE The entry has a data descriptor that contains a signature.

Enum Constant Detail

NO_DATA_DESCRIPTOR

public static final DataDescriptorType NO_DATA_DESCRIPTOR

The entry has no data descriptor.

DATA_DESCRIPTOR_WITHOUT_SIGNATURE

public static final DataDescriptorType DATA_DESCRIPTOR_WITHOUT_SIGNATURE

The entry has a data descriptor that does not contain a signature.

DATA_DESCRIPTOR_WITH_SIGNATURE

public static final DataDescriptorType DATA_DESCRIPTOR_WITH_SIGNATURE

The entry has a data descriptor that contains a signature.

Field Detail

size

public int size

The number of bytes the data descriptor spans.

Method Detail

values

public static DataDescriptorType[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (DataDescriptorType c : DataDescriptorType.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static DataDescriptorType valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
