The template you found is using Eclipse’s built-in code template functions to generate a public static final constant field.

${n:newField(i, true, true, true, true)}${i:inner_expression(novalue)}${cursor}

Breakdown:

${n:newField(i, true, true, true, true)}

This macro tells Eclipse to create a new field.

First argument i -> refers to the type/expression placeholder.

The four true flags mean:

static = true

final = true

initialize = true

public = true

Together, this produces a public static final field (i.e. a constant).

Example expansion:

public static final int MY_CONSTANT = 0;

${i:inner_expression(novalue)}

This defines the “inner expression” placeholder for the field type or value.

(novalue) means it doesn’t prefill anything – you will type in the type/value yourself when the template expands.

${cursor}

This is where the editor caret will be placed after expansion, so you can continue editing from there.

In short:

When you invoke this template, Eclipse auto-generates a public static final constant. You just need to fill in the type (int, String, etc.), the name, and optionally the value.
