Method Detail

expression

public final String expression()

The expression which includes condition names followed by substitution variables, possibly grouped and combined with other conditions. For example, "(starts_with :prefix1 or starts_with :prefix2) and (ends_with :suffix1 or ends_with :suffix2)". Substitution variables should start with ':' symbol.

Returns:

The expression which includes condition names followed by substitution variables, possibly grouped and combined with other conditions. For example, "(starts_with :prefix1 or starts_with :prefix2) and (ends_with :suffix1 or ends_with :suffix2)". Substitution variables should start with ':' symbol.

hasValuesMap

public final boolean hasValuesMap()

For responses, this returns true if the service returned a value for the ValuesMap property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

valuesMap

public final Map<String,String> valuesMap()

The map of substitution variable names to their values used in this filter expression.

Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasValuesMap() method.

Returns:

The map of substitution variable names to their values used in this filter expression.

toBuilder

public FilterExpression.Builder toBuilder()

Specified by:

toBuilder in interface ToCopyableBuilder<FilterExpression.Builder,FilterExpression>

getValueForField
