InferenceInput

equals

public boolean equals (Object o)

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

• It is reflexive: for any non-null reference value x, x.equals(x) should return true.
• It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
• It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
• It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
• For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

getBatchSize

public int getBatchSize ()

The number of input examples. Adopter can set this field to run batching inference. The batch size is 1 by default. The batch size should match the input data size.

getExpectedOutputStructure

public InferenceOutput getExpectedOutputStructure ()

The empty InferenceOutput representing the expected output structure. For LiteRT, the inference code will verify whether this expected output structure matches model output signature.

If a model produce string tensors:

String[] output = new String[3][2];  // Output tensor shape is [3, 2].
 HashMap<Integer, Object> outputs = new HashMap<>();
 outputs.put(0, output);
 expectedOutputStructure = new InferenceOutput.Builder().setDataOutputs(outputs).build();
 

getInputData

public Object[] getInputData ()

Note: use ERROR(InferenceInput.getData()/android.adservices.ondevicepersonalization.InferenceInput#getData() InferenceInput.getData()) instead.

An array of input data. The inputs should be in the same order as inputs of the model.

For example, if a model takes multiple inputs:

String[] input0 = {"foo", "bar"}; // string tensor shape is [2].
 int[] input1 = new int[]{3, 2, 1}; // int tensor shape is [3].
 Object[] inputData = {input0, input1, ...};
 

getParams

public InferenceInput.Params getParams ()

The configuration that controls runtime interpreter behavior.

hashCode

public int hashCode ()

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.

The general contract of hashCode is:

• Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
• If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
• It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
