Constructor Detail

ParsedConstraint

public ParsedConstraint(java.lang.String identifierIn)

This will create a new <code></code> with the specified identifier as the "name".

Parameters:

identifierIn - String identifier for Constraint.

Method Detail

checkConstraint

public ValidatorError checkConstraint(java.lang.Object value)

Check the field against this Constraint to see if it is in a valid state.

Specified by:

checkConstraint in interface Constraint

Parameters:

value - the value to check

Returns:

String error message if the constraint check failed. Null otherwise.

getIdentifier

public java.lang.String getIdentifier()

This will return the identifier for this Constraint.

Specified by:

getIdentifier in interface Constraint

Returns:

String - identifier for this constraint.

setDataType

public void setDataType(java.lang.String dataTypeIn)

This will allow the data type for the constraint to be set. The type is specified as a Java String.

Specified by:

setDataType in interface Constraint

Parameters:

dataTypeIn - String that is the Java data type for this constraint.

getDataType

public java.lang.String getDataType()

This will return the String version of the Java data type for this constraint.

Specified by:

getDataType in interface Constraint

Returns:

String - the data type for this constraint.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

setASCII

public void setASCII(boolean flg)

set the ascii property check

Parameters:

flg - boolean for on/off ascii check

getASCII

public boolean getASCII()

determines whether the ascii property has been set

Returns:

boolean

getUserName

public boolean getUserName()

determines whether the username property has been set

Returns:

boolean

setUserName

public void setUserName(boolean flg)

set the username property check

Parameters:

flg - boolean for on/off username check

isValidUserName

public boolean isValidUserName(java.lang.String s)

small utility to check whether a string is a valid username.

Parameters:

s - string to check for valid username

Returns:

true if string valid

isPosix

public boolean isPosix(java.lang.String s)

Checks whether a string is a POSIX-compliant username - see http://www.opengroup.org/onlinepubs/009695399/basedefs/xbd_chap03.html#tag_03_276 for the definition

Parameters:

s - string to be checked

Returns:

true IFF all chars are a-zA-Z0-9._-, not beginning with -

setPosix

public void setPosix(boolean flag)

Set the posix property check

Parameters:
