io microsphere filter FilterOperator

FilterOperator

Type: Enum | Module: microsphere-java-core | Package: io.microsphere.filter | Since: 1.0.0

Source: microsphere-java-core/src/main/java/io/microsphere/filter/FilterOperator.java

Overview

Enumeration representing various logical operations for combining multiple Filter instances.

Each operator defines how the results of applying multiple filters are combined to produce a final result.

Example Usage

• AND: Returns true only if all filters accept the object.
• OR: Returns true if at least one filter accepts the object.
• XOR: Returns true if an odd number of filters accept the object.

The following example demonstrates how to use the operators to combine filters:

`Filter filter1 = (s) -> s.startsWith("A");
Filter filter2 = (s) -> s.length() > 5;

// Combining filters with AND operator
Filter andFilter = FilterOperator.AND.createFilter(filter1, filter2);
boolean result = andFilter.accept("ApplePie"); // returns true because both conditions are satisfied.

// Combining filters with OR operator
Filter orFilter = FilterOperator.OR.createFilter(filter1, filter2);
result = orFilter.accept("Apricot"); // returns true because at least one condition is satisfied.

// Combining filters with XOR operator
Filter xorFilter = FilterOperator.XOR.createFilter(filter1, filter2);
result = xorFilter.accept("Apricot"); // returns true because only one condition is satisfied.
`

Filter<String> filter2 = (s) -> s.length() > 5;

// Combining filters with AND operator
Filter<String> andFilter = FilterOperator.AND.createFilter(filter1, filter2);

result = orFilter.accept("Apricot"); // returns true because at least one condition is satisfied.

// Combining filters with XOR operator
Filter<String> xorFilter = FilterOperator.XOR.createFilter(filter1, filter2);
result = xorFilter.accept("Apricot"); // returns true because only one condition is satisfied.
