Class UserDefinedAttributeProvider
java.lang.Object
com.google.common.jimfs.AttributeProvider
com.google.common.jimfs.UserDefinedAttributeProvider
Attribute provider that provides the
UserDefinedFileAttributeView
("user"). Unlike most
other attribute providers, this one has no pre-defined set of attributes. Rather, it allows
arbitrary user defined attributes to be set (as ByteBuffer
or byte[]
) and read
(as byte[]
).-
