Constructor Detail

AssemblerInstruction

public AssemblerInstruction(String instrX)

Build an assembler instruction from the instruction format read in.

Method Detail

setTypeAttributes

protected void setTypeAttributes()

setCaseLevels

protected void setCaseLevels(int case_level)

This method will set values to determine what type checking will be used when processing operands. The user is able to set the level of case sensitivity.

Parameters:

case_level - ALL_CASE - Everything is case sensitive except positional operands specified in lower case; DEFAULT_CASE - Upper case positional operands are case sensitive. Text after an equal sign on a keyword is case sensitive. All others are not case sensitive; NO_CASE - Nothing is case sensitive

processValidateOperands

protected int processValidateOperands(String operands)

Validates the operands of an assembler instruction.

validatePositional

protected int validatePositional(String operand,
                                 int start_position)

removeOperandFromString

protected String removeOperandFromString(String operand,
                                         String operands)

charactersValid

public boolean charactersValid(String s1,
                               String s2)

Method charactersValid.

Parameters:

s1 - - The format string

s2 - - The String to check

Returns:

boolean True - If the check string contains all required characters from the parent string. And characters in the check string were all given in upper case. False - If the check string does not contain all the required characters from the parent string or if lower case characters were found in the check string. Examples: s1 = FUNCtion s2 = FUNCT TRUE s1 = FUNCtion s2 = FUN FALSE s1 = FUNCtion s2 = FUNCt FALSE s1 = function s2 = hello TRUE

charactersValidIgnoreCase

public boolean charactersValidIgnoreCase(String s1,
                                         String s2)

Method charactersValid.

Parameters:

s1 - - The format string

s2 - - The String to check

Returns:

boolean True - If the check string contains all required characters from the parent string. False - If the check string does not contain all the required characters from the parent string. Examples: s1 = FUNCtion s2 = FUNCT TRUE s1 = FUNCtion s2 = FUN FALSE s1 = FUNCtion s2 = FUNCt TRUE s1 = function s2 = hello TRUE
