Method Summary

List	getComparisonNames() Gets a List containing the names of the columns in the SQLComparisons.
List	getComparisons() Gets a List containing the SQLComparisons which comprise this ExpressionToken
ValidationExceptionCollection	getValidationExceptions() Deprecated. (6/11/2003 8:18:59 AM) This method will not allow setting the Field's default value from a user property. Replaced by getValidationExceptions(ExecutingContext)
ValidationExceptionCollection	getValidationExceptions(ExecutingContext ec) Be careful when you call this method because it is derived and spins through all the Fields of all the SQLComparisons in this expression token.
boolean	isContainsDisplayParameters() Tests if this expression token contains one or more comparisons which have a display parameter for one or more of their values
boolean	isValueParameterPresent(int index) Tests if at least one of this ExpressionToken's comparisons has a parameter for a value (i.e.
void	setToken(String pToken)
String	toString()

Method Detail

getComparisonNames

public List getComparisonNames()

Gets a List containing the names of the columns in the SQLComparisons.

getComparisons

public List getComparisons()

Gets a List containing the SQLComparisons which comprise this ExpressionToken

getValidationExceptions

public ValidationExceptionCollection getValidationExceptions()
                                                      throws CMException

Deprecated. (6/11/2003 8:18:59 AM) This method will not allow setting the Field's default value from a user property. Replaced by getValidationExceptions(ExecutingContext)

Be careful when you call this method because it is derived and spins through all the Fields of all the SQLComparisons in this expression token. This will return a collection of al; the Exceptions of each Field.

Returns:

collection of validation exceptions.

CMException

getValidationExceptions

public ValidationExceptionCollection getValidationExceptions(ExecutingContext ec)
                                                      throws CMException

Be careful when you call this method because it is derived and spins through all the Fields of all the SQLComparisons in this expression token. This will return a collection of al; the Exceptions of each Field.

Parameters:

ec - context in which code is executing.

Returns:

collection of validation exceptions.

CMException

isContainsDisplayParameters

public boolean isContainsDisplayParameters()

Tests if this expression token contains one or more comparisons which have a display parameter for one or more of their values

isValueParameterPresent

public boolean isValueParameterPresent(int index)

Tests if at least one of this ExpressionToken's comparisons has a parameter for a value (i.e. the value hasn't been specified yet)

setToken

public void setToken(String pToken)

Overrides:

setToken in class SQLToken

toString

public String toString()

Overrides:

toString in class SQLToken
