Constructor Detail

GSERParser

public GSERParser(String value)

Creates a new GSER Parser.

Parameters:

value - the GSER encoded String value

Method Detail

hasNext

public boolean hasNext()

Determines if the GSER String contains at least one character to be read.

Returns:

true if there is at least one remaining character or false otherwise.

skipSP

public GSERParser skipSP()
                  throws GSERException

Skips the input matching zero, one or more space characters.

Returns:

reference to this GSERParser

Throws:

GSERException - If no match could be found

skipMSP

public GSERParser skipMSP()
                   throws GSERException

Skips the input matching one or more space characters.

Returns:

reference to this GSERParser

Throws:

GSERException - If no match could be found

readStartSequence

public GSERParser readStartSequence()
                             throws GSERException

Skips the input matching the start of a sequence and subsequent space characters.

Returns:

reference to this GSERParser

Throws:

GSERException - If the input does not match the start of a sequence

readEndSequence

public GSERParser readEndSequence()
                           throws GSERException

Skips the input matching the end of a sequence and preceding space characters.

Returns:

reference to this GSERParser

Throws:

GSERException - If the input does not match the end of a sequence

skipSeparator

public GSERParser skipSeparator()
                         throws GSERException

Skips the input matching the separator pattern (",") and subsequenct space characters.

Returns:

reference to this GSERParser

Throws:

GSERException - If the input does not match the separator pattern.

nextString
