Field Detail

buffer

protected char[] buffer

A buffer for character level processing; it grows as needed.

delimiterBuffer

protected char[] delimiterBuffer

A buffer to hold the delimiter's characters; it grows as needed.

segmentBuffer

protected java.lang.String[] segmentBuffer

A buffer for building up string segments; it grows as needed.

delimiter

protected java.lang.String delimiter

The delimiter of the value being accessed.

string

protected java.lang.String string

The value being access.

charactersAccessUnit

protected CommonUtil.StringPool.CharactersAccessUnit charactersAccessUnit

An access unit for exclusive use in internString(char[], int, int, int).

Constructor Detail

StringAccessUnit

protected StringAccessUnit(SegmentSequence.SegmentSequencePool.StringAccessUnit.Queue queue)

Create an instance managed by the given queue.

Parameters:

queue -

Method Detail

internString

protected java.lang.String internString(char[] characters,
                                        int offset,
                                        int count,
                                        int hashCode)

setValue

protected void setValue(java.lang.String delimiter,
                        java.lang.String value)

Records the parameters and computes the hash code.

getInternalizedValue

public SegmentSequence getInternalizedValue()

Description copied from class: Pool.AccessUnit

Gets the value that should be added to the pool. This can be specialized to internalized the value, e.g., to make a copy that uses minimal storage or is read only.

Overrides:

getInternalizedValue in class Pool.AccessUnit<SegmentSequence>

matches

protected boolean matches(SegmentSequence value)

Description copied from class: Pool.AccessUnit

Used to determine whether the given value from the pool is equal to the value being accessed. The default implementation uses Object.equals(Object).

Overrides:

matches in class Pool.AccessUnit<SegmentSequence>

ensureSegmentCapacity

protected void ensureSegmentCapacity(int segmentCount)

Ensures that the segment buffer is give enough to hold the given number of segments.

reset

public void reset(boolean isExclusive)

Description copied from class: Pool.AccessUnit

Prepare the access unit for reuse. In particular remove the hard references to each element in both the Pool.AccessUnit.values and Pool.AccessUnit.entries and then reset the Pool.AccessUnit.valuesLength to 0

Overrides:

reset in class Pool.AccessUnit<SegmentSequence>
