Class CodeReaderInputBuffer

java.lang.Object

es.litesolutions.sonar.grappa.CodeReaderInputBuffer

All Implemented Interfaces:

com.github.fge.grappa.buffers.InputBuffer

@Immutable
public final class CodeReaderInputBuffer
extends java.lang.Object
implements com.github.fge.grappa.buffers.InputBuffer

An InputBuffer over a CodeReader

Unfortunately, this is required. Sonar's CodeBuffer claims (claimed?) to support CharSequence, but in fact it doesn't: CharSequence.subSequence(int, int) throws UnsupportedOperationException, which violates the contract. So this is basically a CharSequenceInputBuffer with subsequence extraction rewritten.

Method Detail

charAt

public char charAt(int index)

Specified by:

charAt in interface com.github.fge.grappa.buffers.InputBuffer

codePointAt

public int codePointAt(int index)

Returns the Unicode code point starting at a given index

If the index is greater than, or equal to, the buffer's length, this method returns -1.

Specified by:

Parameters:

index - the index

Returns:

the code point at this index, or -1 if the end of input has been reached

Throws:

java.lang.IllegalArgumentException - index is negative
