Method Detail
-
getSingleton
public static CharSequenceOutputs getSingleton()
-
common
public CharsRef common(CharsRef output1, CharsRef output2)
Description copied from class:OutputsEg common("foobar", "food") -> "foo"
-
subtract
public CharsRef subtract(CharsRef output, CharsRef inc)
Description copied from class:OutputsEg subtract("foobar", "foo") -> "bar"
-
add
public CharsRef add(CharsRef prefix, CharsRef output)
Description copied from class:OutputsEg add("foo", "bar") -> "foobar"
-
write
public void write(CharsRef prefix, DataOutput out) throws IOException
Description copied from class:OutputsEncode an output value into aDataOutput.- Specified by:
writein classOutputs<CharsRef>- Throws:
IOException
-
read
public CharsRef read(DataInput in) throws IOException
Description copied from class:OutputsDecode an output value previously written withOutputs.write(Object, DataOutput).- Specified by:
readin classOutputs<CharsRef>- Throws:
IOException
-
skipOutput
public void skipOutput(DataInput in) throws IOException
Description copied from class:OutputsSkip the output; defaults to just callingOutputs.read(org.apache.lucene.store.DataInput)and discarding the result.- Overrides:
skipOutputin classOutputs<CharsRef>- Throws:
IOException
-
getNoOutput
public CharsRef getNoOutput()
Description copied from class:OutputsNOTE: this output is compared with == so you must ensure that all methods return the single object if it's really no output- Specified by:
getNoOutputin classOutputs<CharsRef>
-
outputToString
public String outputToString(CharsRef output)
- Specified by:
outputToStringin classOutputs<CharsRef>
-
ramBytesUsed
public long ramBytesUsed(CharsRef output)
Description copied from class:OutputsReturn memory usage for the provided output.- Specified by:
ramBytesUsedin classOutputs<CharsRef>- See Also:
