Uses of PObject in org.apache.crunch

Methods in org.apache.crunch that return PObject

PObject<Collection<S>> PCollection.asCollection()


PObject<Map<K,V>> PTable.asMap()
          Returns a PObject encapsulating a Map made up of the keys and values in this PTable.

PObject<S> PCollection.first()


PObject<Long> PCollection.length()
          Returns the number of elements represented by this PCollection.

PObject<S> PCollection.max()
          Returns a PObject of the maximum element of this instance.

PObject<S> PCollection.min()
          Returns a PObject of the minimum element of this instance.

Methods in org.apache.crunch that return PObject
`PObject<Collection<S>>`	`PCollection.asCollection()`
`PObject<Map<K,V>>`	`PTable.asMap()` Returns a `PObject` encapsulating a `Map` made up of the keys and values in this `PTable`.
`PObject<S>`	`PCollection.first()`
`PObject<Long>`	`PCollection.length()` Returns the number of elements represented by this `PCollection`.
`PObject<S>`	`PCollection.max()` Returns a `PObject` of the maximum element of this instance.
`PObject<S>`	`PCollection.min()` Returns a `PObject` of the minimum element of this instance.

Uses of PObject in org.apache.crunch.contrib.bloomfilter

Methods in org.apache.crunch.contrib.bloomfilter that return PObject

static PObject<Map<String,org.apache.hadoop.util.bloom.BloomFilter>> BloomFilterFactory.createFilter(org.apache.hadoop.fs.Path inputPath, BloomFilterFn<String> filterFn)
The method will take an input path and generates BloomFilters for all text files in that path.

static <T> PObject<org.apache.hadoop.util.bloom.BloomFilter> BloomFilterFactory.createFilter(PCollection<T> collection, BloomFilterFn<T> filterFn)

Uses of PObject in org.apache.crunch.impl.dist.collect

Methods in org.apache.crunch.impl.dist.collect that return PObject

PObject<Collection<S>> PCollectionImpl.asCollection()


PObject<Map<K,V>> PTableBase.asMap()
          Returns a PObject encapsulating a Map made up of the keys and values in this PTable.

PObject<S> PCollectionImpl.first()


PObject<Long> PCollectionImpl.length()


PObject<S> PCollectionImpl.max()


PObject<S> PCollectionImpl.min()

Methods in org.apache.crunch.impl.dist.collect that return PObject
`PObject<Collection<S>>`	`PCollectionImpl.asCollection()`
`PObject<Map<K,V>>`	`PTableBase.asMap()` Returns a `PObject` encapsulating a `Map` made up of the keys and values in this `PTable`.
`PObject<S>`	`PCollectionImpl.first()`

`PObject<S>`	`PCollectionImpl.max()`
`PObject<S>`	`PCollectionImpl.min()`

Uses of PObject in org.apache.crunch.lib

Methods in org.apache.crunch.lib that return PObject

static <S> PObject<Long> Aggregate.length(PCollection<S> collect)
          Returns the number of elements in the provided PCollection.

static <S> PObject<S> Aggregate.max(PCollection<S> collect)
          Returns the largest numerical element from the input collection.

static <S> PObject<S> Aggregate.min(PCollection<S> collect)
          Returns the smallest numerical element from the input collection.
