Method Detail

valueOf

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

Returns the encoding associated to a name. If an existing constant exists then it is returned, otherwise a new instance is created.

Parameters:

name - The name.

Returns:

The associated encoding.

equals

public boolean equals(java.lang.Object object)

Overrides:

equals in class Metadata

getParent

public Metadata getParent()

Description copied from class: Metadata

Returns the parent metadata if available or null.

Specified by:

getParent in class Metadata

Returns:

The parent metadata.

hashCode

public int hashCode()

Overrides:

hashCode in class Metadata

includes

public boolean includes(Metadata included)

Indicates if a given encoding is included in the current one. The test is true if both encodings are equal or if the given encoding is within the range of the current one. For example, ALL includes all encodings. A null encoding is considered as included into the current one.

Examples:

• ALL.includes(COMPRESS) returns true
• COMPRESS.includes(ALL) returns false

Specified by:

includes in class Metadata

Parameters:

included - The encoding to test for inclusion.

Returns:
