- Method Detail
  - hasAnd
```
public final boolean hasAnd()
```
    For responses, this returns true if the service returned a value for the And 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.
  - and
```
public final List<Expression> and()
```
    A list of expressions to be combined with AND logic.
    
    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 hasAnd() method.
    
    Returns:
    
    A list of expressions to be combined with AND logic.
  - hasOr
```
public final boolean hasOr()
```
    For responses, this returns true if the service returned a value for the Or 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.
  - or
```
public final List<Expression> or()
```
    A list of expressions to be combined with OR logic.
    
    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 hasOr() method.
    
    Returns:
    
    A list of expressions to be combined with OR logic.
  - not
```
public final Expression not()
```
    An expression to be negated.
    
    Returns:
    
    An expression to be negated.
  - costCategories
```
public final ExpressionFilter costCategories()
```
    Filters based on cost categories.
    
    Returns:
    
    Filters based on cost categories.
  - dimensions
```
public final ExpressionFilter dimensions()
```
    Filters based on dimensions (e.g., service, operation).
    
    Returns:
    
    Filters based on dimensions (e.g., service, operation).
  - tags
```
public final ExpressionFilter tags()
```
    Filters based on resource tags.
    
    Returns:
    
    Filters based on resource tags.
  - toBuilder
```
public Expression.Builder toBuilder()
```
    Specified by:
    
    toBuilder in interface ToCopyableBuilder<Expression.Builder,Expression>
  - builder
```
public static Expression.Builder builder()
```
  - serializableBuilderClass
```
public static Class<? extends Expression.Builder> serializableBuilderClass()
```
  - hashCode
```
public final int hashCode()
```
    Overrides:
    
    hashCode in class Object
  - equals
```
public final boolean equals(Object obj)
```
    Overrides:

```
    Specified by:
    
    equalsBySdkFields in interface SdkPojo
  - toString
```
public final String toString()
```
    Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
    
    Overrides:
    
    toString in class Object
  - getValueForField
```
