Field Details

needsCopying

protected boolean needsCopying

Whether the segments need copying when interned.

needsToIntern

protected boolean needsToIntern

Whether the strings with in the segments needto be interned.

segments

protected String[] segments

The segments being access.

count

protected int count

The number of segments to consider.

Constructor Details

SegmentsAccessUnit

protected SegmentsAccessUnit(SegmentSequence.StringArrayPool.SegmentsAccessUnit.Queue queue)

Creates an instance managed by the given queue.

Method Details

setValue

protected void setValue(String[] value)

Delegates to setValue(true, true, value, value.length).

Overrides:

setValue in class SegmentSequence.StringArrayPool.AccessUnitBase

setArbitraryValue

protected boolean setArbitraryValue(Object value)

Checks of the value is a string array and delegates to setValue(String[]) if that's the case..

Overrides:

setArbitraryValue in class SegmentSequence.StringArrayPool.AccessUnitBase

setValue

protected void setValue(boolean needsCopying,
 boolean needsToIntern,
 String[] segments,
 int count)

Caches the parameters and computes the hash code.

matches

protected boolean matches(String[] 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 SegmentSequence.StringArrayPool.AccessUnitBase

getInternalizedValue

public String[] 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<String[]>

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<String[]>
