Field Detail

OPTION_VERSION

public static final java.lang.String OPTION_VERSION

A save option to specify the BinaryResourceImpl.BinaryIO.Version to be used for the serialization.

Since:

2.7

See Also:

BinaryResourceImpl.BinaryIO.Version, Constant Field Values

OPTION_STYLE_BINARY_FLOATING_POINT

public static final java.lang.String OPTION_STYLE_BINARY_FLOATING_POINT

A Boolean save option to specify whether float and double values are encoded using Float.floatToIntBits(float) and Double.doubleToLongBits(double) respectively, rather than a string representation. The default is true. This style option is only supported for serializations with version 1.1 or higher.

Since:

2.7

See Also:

BinaryResourceImpl.BinaryIO.STYLE_BINARY_FLOATING_POINT, Constant Field Values

OPTION_STYLE_BINARY_DATE

public static final java.lang.String OPTION_STYLE_BINARY_DATE

A Boolean save option to specify whether date values will be serialized using Date.getTime() rather than a string representation. This style option is only supported for serializations with version 1.1 or higher. The default is false.

Since:

2.7

See Also:

BinaryResourceImpl.BinaryIO.STYLE_BINARY_DATE, Constant Field Values

OPTION_STYLE_PROXY_ATTRIBUTES

public static final java.lang.String OPTION_STYLE_PROXY_ATTRIBUTES

A Boolean save option to specify whether serialized proxies will include the serialization of their attribute values. This style option is only supported for serializations with version 1.1 or higher. The default is false.

Since:

2.7

See Also:

BinaryResourceImpl.BinaryIO.STYLE_PROXY_ATTRIBUTES, Constant Field Values

OPTION_BUFFER_CAPACITY

public static final java.lang.String OPTION_BUFFER_CAPACITY

Specify the capacity of the buffered stream used when saving or loading the resource content. The value must be an integer. If not specified, DEFAULT_BUFFER_CAPACITY is used. A value less than one disables the cache.

Since:

2.6

See Also:

Constant Field Values

DEFAULT_BUFFER_CAPACITY

public static final int DEFAULT_BUFFER_CAPACITY

The default OPTION_BUFFER_CAPACITY capacity of the buffered stream used when saving or loading the resource content.

Since:

2.6
