All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`DimensionType`	`getDimensionType()`	Returns the type of this dimension (`DimensionType.StandardDimension` or `DimensionType.TimeDimension`
`Hierarchy[]`	`getHierarchies()`	Returns an array of the hierarchies which belong to this dimension.
`Schema`	`getSchema()`	Returns the schema this dimension belongs to.
`boolean`	`isHighCardinality()`	Returns whether the dimension should be considered as a "high cardinality" or "low cardinality" according to cube definition.
`boolean`	`isMeasures()`	Returns whether this is the `[Measures]` dimension.

Hierarchy[] getHierarchies()
```
    Returns an array of the hierarchies which belong to this dimension.
  - isMeasures
```
boolean isMeasures()
```
    Returns whether this is the [Measures] dimension.
  - getDimensionType
```
DimensionType getDimensionType()
```
    Returns the type of this dimension (DimensionType.StandardDimension or DimensionType.TimeDimension
  - getSchema
```
Schema getSchema()
```
    Returns the schema this dimension belongs to.
  - isHighCardinality
```
boolean isHighCardinality()
```
    Returns whether the dimension should be considered as a "high cardinality" or "low cardinality" according to cube definition. Mondrian tends to evaluate high cardinality dimensions using iterators rather than lists, avoiding instantiating the dimension in memory.
    
    Returns:
    
    whether this dimension is high-cardinality
