public ParseableData(java.lang.String strData)

ParseableData constructor.

Parameters:

StrData - The data to be parsed.

Method Detail

getNextToken

public java.lang.String getNextToken()

Read the next token, delimited by a whitespace, from the data stream.

Returns:

The next token.

nextStringEquals

public boolean nextStringEquals(java.lang.String str)

Check if the current location starts with the string specified.

Parameters:

str - The string to check against.

Returns:

true if the current location starts with the string specified; false otherwise.

nextStringEquals

public boolean nextStringEquals(char[] str)

Check if the current location starts with the string specified.

Parameters:

str - The string to check against.

Returns:

true if the current location starts with the string specified; false otherwise.

nextTokenEquals

public boolean nextTokenEquals(java.lang.String str)

Checks if the next token, delimited by whitespace, is equal to the specified string.

Parameters:

str - String to check the next token against.

Returns:

true if the next token in the data stream is equal to the string specified; false otherwise.

nextTokenEquals

public boolean nextTokenEquals(char[] str)

Checks if the next token, delimited by whitespace, is equal to the specified string (char array).

Parameters:

str - String to check the next token against.

Returns:

true if the next token in the data stream is equal to the string specified; false otherwise.

getNextToken

public java.lang.String getNextToken(char[] delims)

Read the next token, delimited by one of the specified delimiters, from the data stream.

Parameters:

delims - The list of delimiters for the Token.

Returns:

The next Token.

getNextToken

public java.lang.String getNextToken(char delim)
