Method Detail

tokenize

StringMetricBuilder.CollectionMetricTokenizerStep<T> tokenize(Tokenizer tokenizer)

Adds a tokenization step to the metric.

Specified by:

tokenize in interface StringMetricBuilder.CollectionMetricInitialTokenizerStep<T extends Collection<String>>

Parameters:

tokenizer - a tokenizer to add

Returns:

a builder for fluent chaining

filter

StringMetricBuilder.CollectionMetricTokenizerStep<T> filter(com.google.common.base.Predicate<String> predicate)

Adds a filter step to the metric. All tokens that match the predicate are kept.

Parameters:

predicate - a predicate for tokens to keep

Returns:

this for fluent chaining

transform

StringMetricBuilder.CollectionMetricTokenizerStep<T> transform(com.google.common.base.Function<String,String> function)

Adds a transform step to the metric. All tokens are transformed by the function. The function may not return null.

Parameters:

function - a function to transform tokens

Returns:

this for fluent chaining

cacheTokens

StringMetricBuilder.BuildStep cacheTokens(com.google.common.cache.Cache<String,T> cache)

Sets a cache for tokenization chain. The cache will store the result of all previous tokenization steps.

Parameters:

cache - a cache to add

Returns:

this for fluent chaining

build

StringMetric build()

Builds a similarity metric that will use the given simplification, tokenization and filtering steps.

Specified by:

build in interface StringMetricBuilder.BuildStep

Returns:

a string similarity metric.
