Method Detail

addback to summary
public void add(Entry entry)

Add an entry into the Dynamic Table. This will throw if it is not possible to insert this entry. Use canInsert(HttpField) to check whether it is possible to insert this entry.

Parameters
entry:Entry

the entry to insert.

canInsertback to summary
public boolean canInsert(HttpField field)

Is there enough room to insert a new entry into the Dynamic Table, possibly evicting unreferenced entries.

Parameters
field:HttpField

the HttpField to insert into the table.

Returns:boolean

if an entry with this HttpField can be inserted.

canReferenceback to summary
public boolean canReference(Entry entry)
dumpback to summary
public void dump(Appendable out, String indent) throws IOException

Implements org.eclipse.jetty.util.component.Dumpable.dump.

Doc from org.eclipse.jetty.util.component.Dumpable.dump.

Dump this object (and children) into an Appendable using the provided indent after any new lines. The indent should not be applied to the first object dumped.

getAbsoluteback to summary
public Entry getAbsolute(int absoluteIndex)

Get an entry from the Dynamic table given an absolute index.

Parameters
absoluteIndex:int

the absolute index of the entry in the table.

Returns:Entry

the entry with the absolute index.

getBaseback to summary
public int getBase()
getCapacityback to summary
public int getCapacity()
getDrainingIndexback to summary
protected int getDrainingIndex()

Entries with indexes lower than the draining index should not be referenced. This allows these entries to eventually be evicted as no more references will be made to them.

Returns:int

the smallest absolute index that is allowed to be referenced.

public int getInsertCount()
getNumEntriesback to summary
public int getNumEntries()
getSizeback to summary
public int getSize()
getSpaceback to summary
public int getSpace()
indexback to summary
public int index(Entry entry)

Get the relative index of an entry in the Dynamic Table.

Parameters
entry:Entry

the entry to find the relative index of.

Returns:int

the relative index of this entry.

iteratorback to summary
public Iterator<Entry> iterator()

Implements java.lang.Iterable.iterator.

Doc from java.lang.Iterable.iterator.

Returns an iterator over elements of type T.

public String toString()

Overrides java.lang.Object.toString.

Doc from java.lang.Object.toString.

Returns a string representation of the object. Satisfying this method's contract implies a non-null result must be returned.
