CharacterArrayStream

public CharacterArrayStream(char[] content)

Method Detail

hasNext

public boolean hasNext()

Description copied from interface: TokenStream.CharacterStream

Determine if there is another character available in this stream.

Specified by:

hasNext in interface TokenStream.CharacterStream

Returns:

true if there is another character (and TokenStream.CharacterStream.next() can be called), or false otherwise

index

public int index()

Description copied from interface: TokenStream.CharacterStream

Get the index for the last character returned from TokenStream.CharacterStream.next().

Specified by:

index in interface TokenStream.CharacterStream

Returns:

the index of the last character returned

position

public Position position(int startIndex)

Description copied from interface: TokenStream.CharacterStream

Get the position for the last character returned from TokenStream.CharacterStream.next().

Specified by:

position in interface TokenStream.CharacterStream

Returns:

the position of the last character returned; never null

next

public char next()

Description copied from interface: TokenStream.CharacterStream

Obtain the next character value, and advance the stream.

Specified by:

next in interface TokenStream.CharacterStream

Returns:

the next character

isNext

public boolean isNext(char c)

Description copied from interface: TokenStream.CharacterStream

Determine if the next character on the sream is the supplied value. This method does not advance the stream.

Specified by:

isNext in interface TokenStream.CharacterStream

Parameters:

c - the character value to compare to the next character on the stream

Returns:

true if there is a next character and it is the supplied character, or false otherwise

isNext

public boolean isNext(char nextChar1,
                      char nextChar2)

Description copied from interface: TokenStream.CharacterStream

Determine if the next two characters on the stream match the supplied values. This method does not advance the stream.

Specified by:

isNext in interface TokenStream.CharacterStream

Parameters:

nextChar1 - the character value to compare to the next character on the stream

nextChar2 - the character value to compare to the character immediately after the next character on the stream

Returns:

true if there are at least two characters left on the stream and the first matches nextChar and the second matches followingChar

isNext

public boolean isNext(char nextChar1,
                      char nextChar2,
                      char nextChar3)

Description copied from interface: TokenStream.CharacterStream

Determine if the next three characters on the sream match the supplied values. This method does not advance the stream.

Specified by:

isNext in interface TokenStream.CharacterStream

Parameters:

nextChar1 - the character value to compare to the next character on the stream

nextChar2 - the character value to compare to the second character on the stream

nextChar3 - the character value to compare to the second character on the stream

Returns:

true if there are at least two characters left on the stream and the first matches nextChar and the second matches followingChar

isNextAnyOf

public boolean isNextAnyOf(char[] characters)

Description copied from interface: TokenStream.CharacterStream

Determine if the next character on the stream matches one of the supplied characters. This method does not advance the stream.

Specified by:

isNextAnyOf in interface TokenStream.CharacterStream

Parameters:

characters - the characters to match

Returns:

true if there is a next character and it does match one of the supplied characters, or false otherwise

isNextAnyOf

public boolean isNextAnyOf(String characters)

Description copied from interface: TokenStream.CharacterStream

Determine if the next character on the stream matches one of the supplied characters. This method does not advance the stream.

Specified by:

isNextAnyOf in interface TokenStream.CharacterStream

Parameters:

characters - the characters to match

Returns:

true if there is a next character and it does match one of the supplied characters, or false otherwise

isNextWhitespace
