Constructor Detail

StringConstraint

public StringConstraint(java.lang.String identifierIn)

This will create a new Constraints 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

Overrides:

checkConstraint in class ParsedConstraint

Parameters:

value - the value to check

Returns:

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

setMaxLength

public void setMaxLength(java.lang.Double maxLengthIn)

Set the max length of the Constraint

Parameters:

maxLengthIn - The maxLength to set.

getMaxLength

public java.lang.Double getMaxLength()

Returns:

Returns the maxLength.

hasMaxLength

public boolean hasMaxLength()

This will return true if a maximum length constraint exists.

Returns:

boolean - whether there is a constraint for the maximum legnth (inclusive)

setMinLength

public void setMinLength(java.lang.Double minLengthIn)

Set the minimum length of the Constraint

Parameters:

minLengthIn - The minLength to set.

getMinLength

public java.lang.Double getMinLength()

Returns:

Returns the minLength.

hasMinLength

public boolean hasMinLength()

This will return true if a minimum length constraint exists.

Returns:

boolean - whether there is a constraint for the minimum legnth (inclusive)

setRegEx

public void setRegEx(java.lang.String regExIn)

Sets the regular expression for the Constraint. Must be a String containing a valid Java egular expression pattern

Parameters:

regExIn - Java Reg Ex to validate the field against

getRegEx

public java.lang.String getRegEx()

Returns the regular expression

Returns:

regular expression to validate against

hasRegEx

public boolean hasRegEx()

Returns:

True if a reg ex has been set, false otherwise
