argument

@Nullable
protected String argument

Current argument.

Constructor Detail

ParameterizedArgument

public ParameterizedArgument()

Creates a new instance of ParameterizedArgument with the default separator character of semicolon (";").

Method Detail

generate

public StringBuilder generate(StringBuilder sb)

Appends the current argument to the StringBuffer sb.

Specified by:

generate in class CharacterSeparatedList

Parameters:

sb - the StringBuffer to append the argument

Returns:

the StringBuffer with the appended argument.

getArgument

@Nullable
public String getArgument()

Returns current argument.

Returns:

current argument

initializeNbParameters

protected abstract void initializeNbParameters(int nbParameters)

Initialize the number of parameters to read for this argument. Subclasses should override this abstract method.

Parameters:

nbParameters - the number of parameters

initializeNbTokens

protected void initializeNbTokens(int nbTokens)

Initialize the number of tokens.

Specified by:

initializeNbTokens in class CharacterSeparatedList

Parameters:

nbTokens - the number of tokens this instance can handle.

newParameter

protected abstract void newParameter(int id,
                                     int startKey,
                                     int stopKey,
                                     int startValue,
                                     int stopValue)

Reads a new parameter. A key-value pair is parsed from the current string argument. The key part will be a substring from index startKey to index stopKey. The value part will be the substring from index startValue to index stopValue.

Parameters:

id - id for this parameter

startKey - the start index of searching the key substring in current argument

stopKey - the stop index of searching the key substring in current argument

startValue - start index of searching the value substring in current argument

stopValue - stop index of searching the value substring in current argument

ContentType.newParameter(int, int, int, int, int), QualityArgument.newParameter(int, int, int, int, int)

newToken

protected void newToken(int id,
                        int start,
                        int stop)

Adds a new token to the array of tokens. The search will begin from the index start to the index stop.

Specified by:

newToken in class CharacterSeparatedList

Parameters:

id - the ID of the token

start - start index of parameter search in the current string

stop - end index of parameter search in the current string
