Method Detail

getWords

public int getWords()

Description copied from class: PathSegment

Obtain the number of 16-bit words needed to encode this segment instance in padded format. The default implementation assumes the padded format is simply the size of the packed format, rounded up to an even number of bytes.

Overrides:

getWords in class PathSegment

Returns:

Number of words, assuming put() will be called with padded true.

getBytes

public int getBytes()

Description copied from class: PathSegment

Obtain the number of bytes needed to encode this segment instance in packed format.

Specified by:

getBytes in class PathSegment

Returns:

Number of bytes, assuming put() will be called with padded false.

simpleString

public java.lang.String simpleString()

Description copied from class: PathSegment

Supply s simple descriptive name usable when browsing a hierarchy. A simple type name for elementary types, a non-detailed description for complex types.

Specified by:

simpleString in class PathSegment

Returns:

getTokens

public java.util.List<java.lang.String> getTokens()

Specified by:

getTokens in class PathSegment

set

public PathSegment set(java.nio.ByteBuffer source,
                       boolean padded)

Description copied from class: PathSegment

Replace the current instance content with the decoded source bytes.

The caller must ensure that the instance is appropriate for the bytes supplied. This permits instance re-use in optimized applications.

Specified by:

set in class PathSegment

Parameters:

source - The bytes to be decoded. The position will be left after the last byte of the decoded segment.

padded - Alternate format selection. Packed format when false.

Returns:

The same instance.

put

public void put(java.nio.ByteBuffer dest,
                boolean padded)

Description copied from class: PathSegment

Encode the current instance to the given destination.

Specified by:

put in class PathSegment

Parameters:

dest - The buffer receiving the complete encoded instance.

padded - Alternate format selection. Packed format when false.

getData

public short[] getData()

setData

public void setData(short[] data)

compareTo

public int compareTo(PathSegment o)

Specified by:

compareTo in interface java.lang.Comparable<PathSegment>

Overrides:

compareTo in class PathSegment

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object
